Designed for thermal-intensive applications with high EMI constraints, our T-series high-temperature Triacs provide a cost-effective solution with improved EMC immunity and commutation for a wider range of loads.
Based on ST Snubberless technology, T-series Triacs offer higher specified turn-off commutation and noise immunity levels up to 150 °C without the need for an RC snubber.
Designed for on/off or phase-angle control in general-purpose AC switching applications with loads up to 3.5 kW, our new T2535T-8 series is available in three different ECOPACK2-compliant packages, ensuring the best fit for your design:
- T2535T-8T: TO-220AB package safely optimizes the control of motor and heater loads for the most constraining home appliances environments.
- T2535T-8I: TO-220AB insulated package provides a UL-recognized component isolation rated at 2500 VRMS.
- T2535T-8G: SMD D2PAK package is suitable for automatic assembly lines.
